We divide 971438 by 7
The aim is to understand the frequency of 7 in 971438.

On to step 1:
If we divide 9 by 7, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 7 from 9 leaves us with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 7

Advancing to step 2:
The number 7 fits into 27 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 21 from 27 leaves us with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 7

Moving on to step 3:
7 can be fit into 61 8 times, resulting in a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 138.0
Deduct 56 from 61 and we're left with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 7

Let's proceed to step 4:
7 goes into 54 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 1387.0
Deduct 49 from 54 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 7

Step 5:
53 divided by 7 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 13877.0
Subtracting 49 from 53 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 7

On to step 6:
48 divided by 7 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 138776.0
If we take 42 away from 48, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
When dividing 60 by 7, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 138776.8
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
When dividing 40 by 7, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 138776.85
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 138776.857
Deduct 49 from 50 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
7 goes into 10 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 138776.8571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 138776.85714
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 138776.857142
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 138776.8571428
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 138776.85714285
Deduct 35 from 40 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 138776.85714285, and the remainder is 5e-09.
